Response to I have a sta-rite max E-therm 200 pool heater. when the heater fires up all is good, no errors. It runs about 3 or 4 min and the burner shuts off then run another min or two and burner cycles on again. it just keeps doing this. I backwashed, filters are clean, no obstructions. I turned backwash valve to recirculate and it still does this. thank you
